Hi and welcome to the forum.
I too am a carer for my elderly Mum (91) who has been in the diabetic range, albeit around the lower end, for a number of years now, and has also developed other medical conditions that make mobility a challenge for her at times. She also has very traditional tastes, i.e. meat and 2 veg, so changing her diet has always been a struggle, even when she was able to cook for herself and my Dad. Having taken over the cooking over the last few of years, and being diagnosed with Type 2 myself two years ago I have tried to change her diet slightly to bring both our levels down so I appreciate the struggle you're having with her meals. We had managed to get her level to down to 46 at her HbA1c test two years ago, but the last test she had at the end of last year came back at 50 mmol/mol. This concerned me and at her Diabetes Review with the Nurse I voiced my concerns about it going up again, but was told that at my Mum's age they were happy with the figure and it was okay for someone her age. My Mum's (and my) downfall is biscuits and cake, but the odd treat or two may mess with her blood/glucose levels but I personally think her quality of life is slightly more important at her age.
A few years back I asked my Mum if she minded me contacting her Health Centre so that I could talk to them directly about her health and care, so a letter to her Doctor, as requested, and signed by my Mum was put on her records along with my mobile as the main point of contact eg for appointments and text messages. If your Mum is happy to do so, sign up to the NHS App, which you can also access via a computer, so that she or you can log-in and check on her HbA1c results and more. If you're not already registered with the App, your Mum's Health Centre may need to give you access. The other thing I did was to sign up to my regional carers group (ask the Health Centre for contact details). With Devon Carers I got a card that I carry with me in my phone case so that if I have any problems speaking with anyone about my Mum's care I can show them the card to let them know they can talk to me. There's also some other benefits, including free or cheap access to local attractions, social events just for carers and if ever needed, the emergency services can see I'm a carer, contact Devon Carers who can take appropriate action with regards to my Mum.
You mentioned a 14 week course in your initial post. I wondered if you'd thought of asking if you can take the course instead of your Mum? Whether you realise it or not
you are a Carer and as such you should have access to these courses. The main Diabetes UK website has a great learning resource with lots of information and videos from experts and people living with diabetes. The NHS also have a free course, which can be found here
